For over 80 years, Westerbeke has been offering durable and reliable power solutions to meet the challenges of commercial
and recreational marine applications. We manufacture diesel and gasoline fueled generators, diesel propulsion engines,
climate control systems and specialized sound enclosures.
Our products offer quiet operation, low vibration, long service life and superb value. And our track record for
delivering industry-changing innovations has resulted in important advances in safety, as well as beneficial reductions
in size, weight, noise, fuel consumption and exhaust emissions for both generators and propulsion engines.
Today, Westerbeke is recognized worldwide for the quality of our products — and for the outstanding service and
warranty support we provide through a network of Master Distributors and dealers, covering every ocean and sea
plus all the temperate continents.
If our website fails to answer any question or requirement you may have, we hope you will
contact us for a personal response.
Westerbeke understands that marine applications place products in tight spaces and corrosive environments. We engineer
our products not only to provide reliable operation but to run smoothly, since vibration afloat is especially problematic.
Precisely balanced shafts, tuned air intakes, low-RPM engine speeds, carefully considered mounts, stainless steel
Sound Guard SST bases–these are typical key factors in developing Westerbeke products.
Reliability is certainly a convenience for our recreational users, but we are acutely aware of Westerbeke use in
fire-rescue, law enforcement and national defense situations where reliability can make the difference between
success and failure. The length and comprehensiveness of our warranty coverage underscores our belief in the reliability
of all Westerbeke products.
Low-RPM operation extends the service life of our products in addition to reducing fuel consumption, running noise
and engine stress. Our propulsion engines combine these attributes with high torque to provide very useful capability
in moving displacement hulls, a factor which has made these engines especially popular for sailing auxiliaries.
Some Westerbeke generators are quieter unshielded than fully-enclosed competitors' gensets. We also offer the most
advanced sound-shield enclosures in our Sound Guard SST systems. And with Rotary Aire, we bring sound-reduction
to its optimum in compact climate control, for heating and air conditioning.
Westerbeke has been an innovator in changing the way things are done in marine systems. Many credit Westerbeke with
bringing diesel propulsion to recreational boating and a number of the company’s breakthrough products have been
acknowledged in the marine press for decades.
Of more recent interest are Westerbeke’s D-NET™ diesel generators; the first generators available fully networked
to NMEA 2000®. Westerbeke foresaw the increased complexity of wiring larger yachts, providing power supply and
data/command lines for a huge array of navigation, entertainment, safety and lifestyle electronics.
Another important achievement is Westerbeke’s introduction of the first EFI generators to the marine market. Westerbeke’s
leadership in the reduction of carbon monoxide (CO), a lethal byproduct of internal combustion, from the exhaust
stream of gasoline-fueled marine generators has been recognized with the marine industry’s highest award for innovation
as well as by government agencies. Westerbeke also responded to the needs of smaller powerboats whose rapidly escalating
onboard electronics yet very limited space availability now require tiny electrical generators. That led to Westerbeke’s
3.0 BPMG generator, another winner of the industry’s highest award for innovation.
While these innovations are very well known, Westerbeke has many others which help the company remain at the forefront
of the industry. Some are related to the Engineering and Manufacturing processes, such as: a fully integrated Pro-E
Wildfire CAD/CAM system, linked to our CNC equipment for rapid prototyping and assuring adherence to incredibly
tight manufacturing tolerances; an in-factory fully-accredited and calibrated emissions testing laboratory certified
to full federal governmental regulatory compliance standards; multiple stereolithography & fused deposition
modeling rapid prototyping systems; 7 fully equipped Engineering developmental test cells, 3 with dynamometers
and one with a walk-in wide temperature range environmental chamber.
With the introduction of EFI gasoline generator products to the marine market, Westerbeke was able to offer the
first alternative to typical gasoline-fueled products. Westerbeke's leadership in the reduction of carbon monoxide
(CO), a lethal byproduct of internal combustion, from the exhaust stream of gasoline-fueled marine generators made
an additional level of protection available to the industry. Westerbeke's EFI gasoline generators have been recognized
with the marine industry's highest award for innovation as well as by government agencies.
Westerbeke marine propulsion engines all feature standard low oil pressure and high water temperature alarms while
Westerbeke, D-NET™ generators offer an array of safety devices to the diesel generator market. All standard models
include an AC circuit breaker or field breaker and safety shut-downs that include: overspeed, underspeed, low oil
pressure, high exhaust and high coolant temperature. Digital displays also offer LEDs for quick operational status
and an LCD to provide more detailed operational information. In addition, all Sound Guard SST enclosures feature
a standard fire port.
